For many years, the Hu'i Wing, a massive magical brazier that revealed the future and was one of the most valued relics of Koryo, was the centerpiece of a shrine near Goisho. It was tended to by the Wing-ta order of monks. However, some ten generations before 1357 DR, Kozakuran forces stole the Hu'i Wing and carried it off to Karak, and they built it into their fortress there.[2]
